Basic Information Of Sludge Dewatering Machine
High quality sludge dewatering machine is a kind of continuous operation of sludge treatment equipment, because of the low sludge moisture content, stable operation, small energy consumption, relatively simple control and management, good effect, convenient maintenance and other characteristics, by the public favorite.
Because the sludge is concentrated or digested, it is still in a liquid flow state, the volume is still very large, can not be transported and disposed of, in order to further reduce the moisture content, so that the sludge moisture content is as low as possible, the sludge must be dewatered to reduce the sludge volume and facilitate transportation. Sludge is the inevitable product of sewage treatment plant and sewage station sewage treatment. After the sludge that has not been well treated enters the environment, it will directly bring secondary pollution to water and atmosphere, and also pose a serious threat to the ecological environment and human activities. Therefore, the sludge in the treatment is very careful, sludge in the treatment can be divided into two kinds of sludge dewatering process and sludge drying process, the following mainly introduces the respective advantages of different types of sludge dewatering machine. 
The sludge of sewage treatment plant roughly includes: physical and chemical sludge, biochemical sludge, physical, chemical and biochemical mixed sludge and other three kinds. There are certain differences in the adaptation of various sludge to the dewatering machine. The common models of domestic high-quality sludge dewatering machine are: centrifugal, filter belt, spiral ring and plate frame. The dewatering of precipitated sludge, the selection and ratio of flocculant operation is very critical, the flocculation effect is good, the sludge dewatering is relatively smooth. The following brief introduction of the actual use of the three models for selection: Centrifugal: all three kinds of sludge can be adapted, but high energy consumption and high speed lead to high noise. Filter belt type: suitable for physical and chemical sludge, and low moisture content of filter cake, good effect, poor adaptability to mixed sludge and biochemical sludge, reflux sludge, backwashing water consumption, high energy consumption, complex maintenance. Spiral RING type: THE first GENERATION DEwatering machine represented by Japanese prototype has been promoted and applied for 3-4 years in China, but its disadvantage is low output. High quality sludge dewatering machine has the advantages of small size, good effect, low energy consumption, low noise, no vibration, high degree of automation, convenient centralized management, convenient maintenance and so on. Mainly used for: 1. Industrial wastewater coagulates and precipitates sludge 2. Industrial wastewater excess activated sludge 3. Urban sewage treatment of surplus sludge 4. Community sewage treatment sludge 5. Add medicine to coagulate sludge in water purification field 6. Water and fertilizer treat the remaining sludge 7. Solid-liquid separation in factory manufacturing process
